Nailed by BizTalk

I got nailed by what seems to be a BizTalk bug yesterday. I found a resolution on Victor Fehlberg's blog. Thanks, Victor! The issue occurs when deploying an MSI that has a map that uses an external assembly. If the map was created when the external assembly was compiled with Debug configuration, the map won't be able to find the assembly compiled with the Release configuration.

Victor's issue was slightly different, so here is the (very ambiguous) error message that I saw. I'm including it here to make it easy to search with Google, and so that I can find this in the future:

I resolved the issue by opening the map in my text editor and replacing all instances of "\obj\Debug\" with "\obj\Release\"
